Overview

The 1N5955PE3/TR8 is a Zener diode with a single common-cathode construction. It is rated for a peak reverse voltage of 18 V, a continuous reverse voltage rating of 16.7 V, and a maximum forward voltage of 2.4 V. It has a small outline and offers higher power dissipation than typical Zener diodes.

Application Field

The 1N5955PE3/TR8 is ideal for general-purpose switching, load-switching, voltage clamping, and signal protection applications. It’s high-power dissipation capability also makes it well-suited for use in power regulator circuits.

Working Principle

The 1N5955PE3/TR8 is a Zener diode with a single common cathode construction. It has a relatively low forward voltage drop which helps to keep losses to a minimum. The peak reverse voltage of 18 V allows it to be used in high voltage applications. When forward biased, it allows current to flow in a single direction. Conversely, when reverse biased, it provides a stable voltage reference. Zener diodes are typically used to limit the amount of reverse voltage that can be applied to connected circuitry.

Conclusion

The 1N5955PE3/TR8 is a Zener diode with a single common cathode construction, rated for a peak reverse voltage of 18 V and a forward voltage of 2.4 V. It is well-suited for general-purpose switching, load-switching, voltage clamping, and signal protection applications due to its high power dissipation capability and relatively low forward voltage drop. When forward biased, it allows current to flow in a single direction and when reverse biased, it provides a stable voltage reference. In summary, the 1N5955PE3/TR8 is a reliable and effective Zener diode for a variety of applications.
